Absolute ethanol cannot be obtained by simple fractional distillation of a solution of ethanol and water because:

$A$ liquid mixture that boils without changing its composition is called:

The boiling point of an azeotropic mixture of water and ethanol is less than that of both pure water and pure ethanol. The mixture shows:

What is the approximate percentage by mass of aqueous $HNO_3$ that can be obtained by distillation (in $\%$)?

Which one of the following mixtures can be separated into pure components by fractional distillation?

Components of a binary mixture of two liquids $A$ and $B$ were being separated by distillation. After some time,the separation of components stopped and the composition of the vapour phase became the same as that of the liquid phase. Both the components started coming in the distillate. Explain why this happened.
